1. An induced draft air-cooled condenser comprising:
a vertical centerline axis;
a support structure;
a pair of inclined tube bundles supported by the support structure, the tube bundles each comprising a plurality of tubes;
the tube bundles defining an interior space in fluid communication with ambient air through the tube bundles;
a fan supported above the interior space along the vertical centerline axis, the fan comprising fan blades disposed inside an annular fan shroud; and
a drive mechanism operable to rotate the fan blades, the drive mechanism comprising a motor coupled to the fan blades and located inside the fan shroud;
wherein the fan is operable to draw ambient air through tube bundles into the interior space;
wherein the fan and motor are mounted to and supported by a horizontal planar fan bridge spanning across and over the interior space inside the fan shroud, the fan bridge configured and structured to provide support for personnel to access the fan and motor;
wherein the fan bridge is supported at its ends by a horizontal planar peripheral fan deck disposed outside and extending circumferentially around the fan shroud, the peripheral fan deck supporting the fan shroud at a circular central airflow opening defined by the peripheral fan deck;
wherein the fan shroud comprises an access opening aligned with the fan bridge and arranged to allow personnel to access the fan bridge directly through the fan shroud.
